Abstract: A hydrogeological investigation was carried out in Haringhata Block, Nadia district, West Bengal to understand
the groundwater scenario in the block. The groundwater condition and the stratigraphy were analyzed at seventeen sites of
the study area. The rainfall-groundwater dynamics was also analyzed to understand the recharge condition in the study area.
Groundwater level data was used for preparation of pre- and post-monsoon groundwater depth contour maps and a
groundwater fluctuation map. The analysis of 5 years (2004-2008) seasonal groundwater level data of 17 sites indicated
appreciable groundwater fluctuations over the area. The groundwater drops 5 to 8 m from the ground surface at most sites
during the dry season, whereas, mean post-monsoon (November) groundwater depth varies from 2 to 4 m. It is concluded that
long-term monitoring of groundwater level and understanding the rainfall-groundwater dynamics are helpful for formulating
strategies for sustainable development and management of groundwater resources in the study area.

1. INTRODUCTION
Groundwater plays a central role in maintaining and ensuring the ecosystem and livelihood security of this planet.
Nowadays groundwater has become a very dependable and popular freshwater resource in both urban and rural areas of
our country due to it’s easy and ensured availability at the required time. The socio-economic dependency on groundwater
can be explained over a wide range of factors [1]. Recent research shows that groundwater irrigation has overtaken
surface-water irrigation as the main supplier of water for India’s crops. Quantitative and qualitative aquifer mining is the
major outcomes of this unplanned over-exploitation of groundwater resources [2]. Therefore, policy makers must rise to
the challenge of finding ways to manage groundwater resources sustainably.
Haringhata Block located in southern part of Nadia district, West Bengal is suffering from water shortage problems both
qualititatively and quantitatively. As the main occupation of the local people is agriculture, the water scarcity problem
greatly hampers the socio-economic condition in the area. The block is mainly irrigated through extraction of ground
water. There are 3477 shallow tube wells, 42 Deep Tube wells run by the Department of Agri-irrigation, Govt. of West
Bengal. The existing surface irrigation sources are not sufficient to ensure proper quantity of water at required time due to
the erratic nature of the rainfall in the country. Therefore, groundwater becomes an inevitable source of water supply in
the study area. However, the unrestricted excessive pumping of groundwater has resulted in groundwater lowering
problem in the area in past few years. In addition to that, the area has an arsenic contamination problem. The detrimental
health effect has increased in recent years because of increased use of tube wells. Therefore, there is an urgent need to
develop management strategies for the sustainable utilization of groundwater resources in the study area. With this
background, a hydrogeological investigation was carried out to understand the groundwater scenario in Haringhata Block,
Nadia district, West Bengal for the sustainable utilization of vulnerable groundwater resource of the area. The objectives of
the present study were (i) to analyze available lithologic data to understand the aquifer system in the area, (ii) to explore
groundwater dynamics in the study area.

2. MATERIALS AND METHODS
2.1 Study Area Description
Haringhata Block, study area of this present study, is located in extreme south of Nadia district of West Bengal. The
geographical extent of Haringhata Block lies within a latitude of 22054/ N to 2302/ N and longitude of 88030/ E to 88041/ E
which covers an area of about 170.32 Sq. Km. The location of the study area is shown in Figure1. The block comprises of 10
Gram Panchayats (GP). The block is bound by Chakdah block in the north and the west. South and east part of the block is
bounded by North 24Parganas District. A small river system which is locally known as Jamuna is flowing through the
block. The soil of the block is mostly clay loamy type. The climate of the block is characterized by oppressively hot
summer, high humidity and high rainfall during the monsoon. Winter starts from the middle of November which continues
up to the end of February. During the monsoon from June to September about 71% of annual rainfall occurs. The rainiest
month is August. The mean annual rainfall is about 1400 mm. Average elevation of the block is 10 m from mean sea level.

2.2 Data Collection and Analysis
Monthly rainfall data for the period of 2004-2008 were collected from the rainguage station monitored by B.C.K.V.,
Mohanpur, Nadia. In addition, the pre-monsoon and post-monsoon groundwater level data for the 2004-2008 period were
collected for 17 sites over the Haringhata Block from State Water Investigation Directorate (SWID), Government of West
Bengal, Kolkata; the location of the sites are shown in Fig 1. These groundwater level data were used for analyzing rainfall-
groundwater dynamics as well as to prepare pre- and post-monsoon groundwater depth contour maps and a groundwater
fluctuation map.
Moreover, the lithologic data at sventeen sites of Haringhata Block, were collected from the SWID, Kolkata. The lithologic
data of different sites were used for stratigraphy analysis to know aquifer types, depth and thickness of main water-
bearing strata and other subsurface layers in the study area.
3. RESULTS AND DISCUSSIONS
3.1 Sratigraphy of the Study Area
The lithologic profiles at 17 sites (Fig. 1) of Haringhata Block are shown in Figure 2. It is apparent from Fig. 2 that the
depth of geologic investigation varies from 100 m to 180 m, except at site G14, where may be due to some difficulties
geologic log covers only 57 m depth. Usually, subsurface formation comprising coarse sand, medium to fine sand, fine
sand, clay are present at most sites. The top soil is predominantly sandy clay or silty clay with a thickness varying from 3
to 7 m. At some sites this clay layer is extended to lower depth. The top soil is underlain by a layer of fine sand to medium
to fine sand at most of the sites. The thickness of this layer varies from 5 to 25 m, except at site G3, where it varies upto 55
m. This layer contains groundwater though this layer is not very reliable for adequate and long-term water supply. The

3.2 Groundwater Characteristic
It is apparent from Fig. 3 that the rainfall is the direct recharge source of groundwater in the area. Fig. 3 indicates that as
the 2008 pre-monsoon rainfall is high compared to previous two years, the pre-monsoon groundwater depth is
comparatively high in 2008. In spite of low monsoon rainfall in 2008 compared to previous two years, as groundwater
level could not be lowered much due to higher pre-monsoon rain in that year, the post-monsoon groundwater level is high,
almost same as previous years in spite of high monsoon rainfall in the previous two years.
The variation of 5-year average pre- and post-monsoon groundwater depths at 17 locations of Haringhata blocks of Nadia
district is shown in Figure 4. It can be seen from the figure that the mean pre-monsoon (April) groundwater level varies
appreciably with a maximum depth of about 8.2 m below the ground surface to a minimum depth of 3.6 m. The standard
deviations are small at most sites indicating that the pre-monsoon groundwater level does not vary appreciably from year
to year. At W13, W16 and W17 sites the error bars are high indicating significant pre-monsoon groundwater level
variation in those sites. The mean post-monsoon (November) groundwater level also varies significantly with a maximum
depth of approximately 5.3 m below the ground surface and a minimum depth of about 1.38 m. The standard deviations
are relatively high for many well locations compared to the pre-monsoon groundwater level, suggesting significant
temporal variation of the post-monsoon groundwater level. It could be also inferred from the Fig. 4 that the range of
groundwater fluctuation in the study are is very less with a maximum fluctuation of about 3.5 m and minimum fluctuation
of 2 m. This indicates a fairly uniform recharge of groundwater throughout the block.

A contour map of mean pre-monsoon (April) groundwater level (2004-2008) prepared from 17 observation well sites
over the study area (Fig. 5-a) reveals that the mean pre-monsoon groundwater depth in the area increases towards
western part of the block with a major portion of the area having 6.5 to 8 m depth. In the south eastern portion of the area,
the pre-monsoon groundwater depth is lower than 4.5 m. On the other hand, the contour map of mean post-monsoon
(November) groundwater level (Fig. 5-b) reveals that the groundwater depth varies from 2 to 4 m.
The groundwater level fluctuation contour map (Fig. 6) reveals that a major portion of the study area has a mean
groundwater fluctuation of 2 to 3.5 m.
3.3 Hydraulic Connectivity in the Study Area
The correlation matrix for the post-monsoon (November month) groundwater-level data from 17 sites over the study area
is presented in Table 1. In Table 1, except for the highlighted correlation coefficient values, all the other correlation
coefficient values are high ( 50.0r )and range from 0.5003 (between W9 and W16) to0.9938 (between W6 and W8).
These findings suggest good hydraulic connection among most sites during post-monsoon period. Only, site W3 has poor
hydraulic connection with most of the sites in the area during post-monsoon period.

4. CONCLUSIONS
The present study aims at carrying out a hydrogeological investigation in Haringhata Block, Nadia district, West Bengal for
the sustainable utilization of vulnerable groundwater resource of the area. The analysis of lithologic profiles of seventeen
sites of the block revealed that subsurface formation usually comprises coarse sand, medium to fine sand, fine sand, clay.
The top soil is underlain by a layer of fine sand to medium to fine sand at most of the sites which contains groundwater,
though this layer is not very reliable for adequate and long-term water supply. Main aquifers are located at deeper depths.
The analysis of the 5-year (2004-2008) pre- and post-monsoon groundwater level data revealed that the mean pre-
monsoon (April) groundwater depth in the area increases towards western part of the block with a major portion of the
area having 6.5 to 8 m depth. In the south eastern portion of the area, the pre-monsoon groundwater depth is lower than
4.5 m. On the other hand, mean post-monsoon (November) groundwater depth varies from 2 to 4 m. The mean
groundwater fluctuation gradually increases from 2 to 3.5 m towards the western part of the study area. On a whole, the
results of the present study will help in developing an efficient and sustainable groundwater utilization plan in the study
area.
